It was the show Down Under Swiftie fans have been counting down the sleeps for.

But thanks to one drunken concert goer, Taylor Swift’s massive gig at the Melbourne Cricket Ground on Friday got off to a horrible start for some fans.

The thoughtless Swiftie threw up on several seats, leaving vomit in an area fans had paid hundreds for.

Fans who had booked the ruined seats had to wait two hours before the disgusting mess could be cleaned up reported news.com.au on Saturday.

According to the report, the incident occurred at 7pm, but it wasn’t until after 9pm that the Swifties were able to return to their seats after standing by for the area to be scrubbed clean.

And by then, Taylor was well into her set.

‘We had to stand in areas near the seats for the majority of Taylor because they took two hours to find someone to clean it up,’ an eyewitness said. ‘It stunk.’

Taylor Swift made history performing to her largest ever crowd on the first night of her Eras Tour in Australia, but some observant ‘Swifties’ have questioned why so many stadium seats were empty.

Fans who were lucky enough to score a seat at the sell-out show took to social media to share images of hundreds of empty seats throughout the Melbourne Cricket Ground.
